Application filed April 4, 1916. Serial N 0. 88,932.

To all whom it may concern:

Be it known that I, WILLIAM a citizen of the United States, residing atCaro, in the county of Tuscola and State of Michigan, have invented newand useful Improvements in Article-Supports for Ladders, of which thefollowing is a specification.

This invention relates to a support for paint buckets, tool boxes or thelike, and

asparticular application to a device for supporting these articles upona ladder. The chief characteristic of this invention- U. BERRY,

' resides in the provision of a device of this character having meansfor automatically adjusting the bracket to support an article 1nvertical position and means for lockingthe bracket in adjusted position.

Another important object of this invens tlon is to provide a device ofthis character having means for clamping the support in Fig. 2 is sideelevation ofthe ladder and article support.

Fig. 3 is adetail view of the support.

eferring more particularly to the drawings, 1 deslgnates the side railof a ladder of any common construction, upon which is arranged an anglebar 2, the latter being formed of any suitable metal and provided at itsupper end with a lateral extending ear 3. Mounted upon the angle bar 2and is a clamping is substantially lL-shaped, the longer arm of themember extending through the ear 3 and having its free extremitythreaded to receive a winged nut 5.

' The short arm of the clamping member 4 is adapted to engage the edgeofthe side v rail 1 whereby u on screwing the nut 5 upon the extremity ofthe long arm, the angle bar 2 will be rigidly secured a to the side railas will be understood.

Pivotally mounted upon the side portion of the angle bar 2 adjacent itslower end is the vertical arm 6 of my improved form of bracket orsupport 7, the vertical arm being pivoted between its ends as at 8.Extending at right angles from the vertical arm 6 of the bracket 7 isthe horizontal arm 9. The upper end of the vertical arm 6 is providedwith a horizontal head 10, the latter being formed with an arcuateshaped slot 11 and receiving a threaded shank 12 formed on the side ofthe angle bar. The threaded end of the shank 12 is adapted to receive awing nut 13, the nut engaging the opposite Walls of the slot to lock thehead 10 and consequently prevent the vertical arm 6 of the bracket fromrocking upon its pivot. I

, Mounted upon the other or free end of the horizontal arm 9 of thebracket is a receptacle 14 which is preferably cylindrical and which hasits under side provided adapted to extend into and through an opening 16formed in the bracket, the free end of the stud being disposed upon 'theunderside of the bracket and threaded to receive a wing nut 17. Thus itwill be seen that the receptacle may be rigidly clamped upon thehorizontal arm 9 of the bracket and positioned so as to receive andsupport a paint bucket, tool box or the like as Will be understood.

It will 'be seen from the foregoing construction that in practice theangle bar is secured to the side rail 1 of the ladder as shown in Fig. 2whereby the nut 5 is rotated to cause the clamping member 4 to securelyhold the angle barupon the ladder. Owing to the fact that the bracket?is pivotally mounted upon the angle bar 2 andassuming that the nut 13 isnot engaging the head 10,. the bracket may be free to' swing orgravitate to vertical position irrespective of the angle of the ladder.Thus it will be seen that the article held within the receptacle 14 willbe supported in vertical position at all times irrespective of the angleof the ladder. The bracket having been permitted'to assume its verticalposition,'the wing nut 13 is then screwed upon the shank 12 so as toengage the walls of the slot 11 whereby the bracket'will be locked inadjusted or vertical position and the maintenance of the article heldwithin the receptacle insured.

with a depending stud 15, the stud being It is thought from theforegoing taken in connection with the accompanying drawings thatthe-construction and operation of my device will be apparent to thoseskilled in the art without further description, and

that minor changes in size, shape, proportion, and minor details ofconstruction may be made'without departing from the spirit and scope ofthe appended claims.

What I claim:

1. A device of the class described ,comprising a bar, a threaded studformed on said bar, means fonsecuring the bar to'the side rail of aladder, a bracket pivotally mounted on the bar, said bar havi a slotformed therein, said stud extending t rough said slot, and a nutprovided on said stud and engageable with the walls of said slot wherebythe bracket will be locked against movement, and a receptacle carried bysaid bracket.

2.. A device of the class described comprising a bracket having avertical arm and a horizontal arm, said bracket adapted to be pivotallymounted upon theside rail of a ladder, said vertical arm being providedwith an arcuate shaped slot, means mounted in, said slot for locking thebracket in adjusted position, and a receptacle carried by the horizontalarm of said bracket.

3. A device of the class described comprising an angle bar, a clampingmember carried by the angle bar whereby the bar may be secured to theside rail of a ladder, a bracket having a vertical and horizontal armconnected at theirends, said vertical arm being pivotally mounted uponsaid bar, a head formed on'the upper end of said bar and provided with aslot, means mounted on said bar and working within said slot for lockingthe bracket against movement, and a receptacle deta'chably mounted uponthe free end of the horizontal arm..-

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM o. BERRY.
